Is CookieManager - Cookie Editor Safe? — Extension Safety Profile

This extension requests the cookies permission, which allows it to read, modify, and delete any cookie in your browser for any website. Combined with host access to *://*/*, it can interact with cookies on all sites you visit. The scripting permission lets it inject code into pages, and contextMenus adds right-click menu options. For a cookie editor, this broad access is expected, as the tool needs full cookie control to function, but it also means the extension has significant power over your browsing sessions and logged-in accounts.

Cookie managers and editors fall into a category where users should be especially cautious. Because they can read session cookies, a compromised or poorly maintained extension could potentially allow an attacker to hijack accounts. The publisher is an individual developer with a limited public track record, which is common for niche utilities but means less external accountability. The fact sheet shows a low community reputation score (57%), driven by a modest rating of 3.4 out of 5 from a small number of reviews, suggesting mixed user satisfaction.

On the positive side, the extension scores well on maintenance and ownership (85%), indicating it has been updated relatively recently and the developer has declared standard privacy practices, including that data is not sold or used for unrelated purposes. However, these are self-declared claims and not independently verified. A careful user should weigh the convenience of cookie editing against the trust required to grant such extensive permissions to a small-scale publisher.
